Semi-submersible rigs and platforms

Semi-submersible rigs and platforms

Sealing systems designed for the world’s most demanding offshore environments. Semi-submersible rigs operate in some of the harshest conditions in the energy industry – exposed to constant movement, saltwater, pressure and extreme weather. CSD’s sealing systems are trusted globally to protect these critical offshore assets, providing long-term defence against fire, water, gas, smoke and electromagnetic pulse (EMP).

Designed for semi-submersible rig and platform demands

Our solutions are engineered to maintain compartment integrity and prevent the spread of hazards between zones, even under dynamic load or vibration. Whether for new-build platforms or life-extension projects, CSD systems deliver certified, maintenance-free performance.
Our Case Studies

Up to 4 hours fire resistance (A-0 to A-60 rated) for full compartment safety

Watertight and gastight integrity tested to 10 bar pressure

Vibration- and corrosion-resistant construction for offshore conditions

Maintenance-free and re-enterable for future upgrades and inspections

Certified protection against fire, water, gas, smoke and EMP

“CSD Technical Services delivered the water, and gastight sealing works to a high standard across our control room and DNO substation. Their support contributed effectively to our wider climate action plan, including the installation of a new solar farm and battery storage system. We were very satisfied with the work and will be considering CSD for future projects.”
